Specification of Letters Patent.

Patented Aug. 4, 1908.

Application filed February 8, 1907. Serial No. 356,338.

To all whom it may concern:

Be it. known that I, JAMES E. BRIGHT, a citizen of the United States, residing at Washington. in the District of Columbia, have invented certain new and useful Improvements in Printers Chases, of which the.

a separate compartments, a plurality of pages being locked in each compartment, said compartments being formed by the outer rim or sides of the chase and cross-bars connecting the opposite sides and made rigid therewith. In locking chases of the character above de scribed it has been necessary to employ quoins and furniture adjacent the sides of each cmnpartmcnt formed of the outer sides of the chase thus forcing the form in each compartment against the cross-bars. In chases thus constructed it has been possible to use only one chase upon the press at a time because of the fact that were two chases placed adjacent upon the bed of the press the s )ace occupied by the adjacent sides of the c ases and the quoins and furniture abutting these sides would be so great as to render the proper folding of the pages impossible by producing varying relations between the printed matter and the edge of the page; and in case the printed sheets are cut centrally so as to fold )roperly an unnecessary waste of paper results. By the use of my invention this s ace is reduced to the desired extentw lereby two chases may be used upon the press at the same time and double the work produced with each impression. To this end I dispense with the use of locking quoins and furniture on one side of the chase and provide means introduced intermediate of the form being locked; whereby the locking p essure of the side opposite the unlocked side is absorbed and uniformly transmitted to the unlocked side. By this construction two chases with their unlocked sides adjacent can be used on the bed of a mass at the same time and a proper fold of the printed sheets had without cutting.

The invention here shown and described illustrates a chase comprising four compare Inenis formed by crossbars, bu it will be c s I l the operation of locking ZS lessened understood that the invention can be readily utilized with advantage in the construction of chases having fewer compartments.

In describingthe invention in detail reference will be had to the accompanying drawing which forms part of this specification and wherein like characters of reference denote corresponding parts in the several views and in which:

Figure 1 is a top plan view of a chase embodying my invention with a form locked therein; another similar chase being shown set up adjacent thereto in dotted lines; Fig. 2 is a longitudinal section on the line rza of Fig. 1. Fig. 3 is a. transversesection on the line bl) of Fig. 1.

In these drawings the chase is constructed of the usual transverse side bars A, and longitudinal side bars B, B; the words lon 'itudinal and transverse being used with ul ation to the longitudinal and transverse axes of the press. The side bar B is of less width than the side bar B as the side bars B abut when a pair of chases are set upon the press for use and thereby occupy less space than if they were the same width as side bar B. The transverse cross-bar C connects the longitudinal side bars B. B centrally and has its respective ends made rigid with the side bars B, B. The bars A, A have cut therein T shaped recesses A A and a recess C is cut centrally of the transverse cross-bar C. A longitudinal cross-bar D connects the transverse side bars'A. A and is capable of limited movement in the direction ofthe said bars A, n. The cross-bar D has its ends D, D formed T shaped adapted to rest in the recesses A, 3 respectively. The shoulders of the T ends of the bar D are shorter than the shoulders of the recesses A, A while the stems of theT recesses A A are wider than the bar D. The said bar D is provided centrally with a recess D corresponding to the recess C in bar C but oppositely disposed thereto and similarly disposed to the recesses A, A and of a width to just easily receive the bar C and allow the bar I) to move forward and backward in the recess C and the recesses A in the direction of the side bars A, A, said rcccsses'C, A and A being suiliciently lon; to permit of the desired movement of he bar D. The 0 positely dis osed recesses (1" and D cause tlib bars C an D to loosely inte' ocl-r in a manner that th ir t-zp and button" mu xccs register, while the bar has its iltl: supper! at D" and D" whereby the top and bottom surfaces of the bar D register with the top and bottom surfaces of the bars A and A.

The bar D is held againstdisplacement from its seat in the recesses A A by the cross-bar U which straddles the bar 1) centrall the bar D being first placed in position in assembling xviz its stepped ends resting in the recess. A, A then secured in place by having its ends welded to the side oars B, B, said bar C overlying the bar D and preventing its displace- In the drawing the oar C- 15 shown ment. integral with the bars B, B as the welding of the ends of the bar L to sait. bars B, B renders the bars B, B and the bar C substan tially one piece.

The manner of locking the chase through the medium of the movement of the crossbar D will be apparent. Through the utilization of the bar D constructed as shown all quoins along the side bar B are dispensed with. The quoins along the side bar B when 0 erated serving to force the cross-bar D in t 1e direction of the side bar B and thus clamping the forms between the side bar B and the movable cross-bar D. Y

Having thus described my invention what- I claim as new and desire to secure by Letters Patent i:

1. In a printcrs chase an outer frame. dividing members or member forming a plurality of form compartments in said chase, and means whereby said chase is adapted to be locked from three sides, the unlocked side being parallel to a dividing member.

2. In a printer's chase, an outer frame, a

dividing member forming a lurality of form compartments, and means \v iereby the chase is adapted to be locked from three sides pressure in locking being transmitted in the unlocked side through the medii :1 of the dividing member.

3. A printers chase having an inc-losing frame, a plurality of form com art-dents formed by cross-bars within said rame d means for locking the compartments from three sides of the inclosing frame.

4. A printer's chase having an inclosing frame, a plurality of form compartments formed within said frame and means whereby said chase is adapted to be locked from three sides and the pressure transmitted to the unlocked side.

5. A "irint-ers chase having an inclosing frame a apted to be locked from three sides,

a member connecting opposite sides of the frame and forminga lurahty of form compartments said mem or being adapted to transnnt pressure in looking to the unlocked side.

The bar is I 6. A rintcrs chase having an inclosing frame at apted to be locked from three sides, i a movable member connecting o posite sides of the frame whereby a pluraiity of form com 'iartments is formed and the pressure transmitted in locking to the unfocked side. A printer's chase having an inclosing 5 frame adapted to be locked from three sides. a movable member conne ting opposite sides 5 of the frame whereby a plural ty of form compartments is formed and the pressure lockmg tr.-tns1nitted to the unlocked side and means for securing the movable member against displacement.

8. A printers chase hav ng an inclosing frame adapted to be locked from three sides. a movable member connecting opposite sides of the frame whereby a plurality of form compartments is formed, a second member connecting and rigidl secured to the liter 0pposite sides of the frame ada ted in secure the movable member against 1 isplacement.

9. A printers chase having an inclosing frame, a plurality of form compartments formed within said frame and means where- I by said chase is adapted to be locked from three sides and the pressure transmit ted uniformly intermediate of the form being locked to the unlocked side.

10. A printers chase having an inclosing frame adapted to be locked from three sides, a movable member connecting opposite sides of the frame, a second member connecting and rigidly secured in the other opposite sides of the frame, wherein a plurality of form compartments are formed. a recess in the fixed member in which the movable i member rests and has a l mited movement.

11. A printers chase adapted to be loci-zed from three sides and means intermediate of the form to transmitting pressure to the unlocked side from the locked side opposite thereto.

12. A printers chase having a plurality of form compartments and adapted to be locked from three. sides and means intermediate of "he form for t-ransmitting ressure to the unloc ed aid" from the loc'ed side opposite tin it.

. 13. i" m r'al form printers chase adapted to be loc ked from three sides and movable v means independent of and cooperating with the type and furniture for transmitting pressure. against the unlocked side.

In testimony whereof l affix my signature in the presence of two witnesses.
